&#34;June Lion&#34; nectarine tree

ABSTRACT

A new and distinct variety of nectarine tree which is somewhat remotely similar to the “Spring Bright” nectarine tree (United States Plant Pat. No. 7,507), but from which it is distinguished by producing fruit which are mature for harvesting and shipment approximately five days to seven days prior to the fruit produced by the, “Spring Brighf” nectarine tree in the San Joaquin Valley of central Califoinia and wherein the fruit is of high quality having a skin coloration of dark garnet red over nearly the entire surface thereof.

BACKGROUND OF THE NEW VARIETY

[0003] The present invention relates to a new and distinct variety of nectarine tree, which will hereinafter be denominated varietally as the “June Lion” nectarine tree, and, more particularly, to a nectarine tree which produces amber-yellow fleshed fruit, having a skin with a moderately uniform red blush color, which are mature for commercial harvesting and shipment approximately June 16 through July 1 in the San Joaquin Valley of central California, depending upon the particular growing year.

[0004] The discovery and development of new tree fruit varieties takes place in many areas of the world. It is a prodigious task, but one which has the potential for significant rewards. This is particularly the case in the San Joaquin Valley of central California. Much of this discovery and development has taken place in the San Joaquin Valley through more than a century of effort by a multiplicity of different individuals, business entities, research institutions, universities and the like.

[0005] Because of the efforts expended over many decades, the selection of new varieties is difficult. The new varieties must be sufficient advancements over the prior art to warrant the considerable costs required to develop such new varieties and achieve fil commercialization of their product. The period of time which has transpired in such developmental efforts has resulted in the development of untold numbers of varieties of tree fruit which frequently makes selection of promising varieties difficult and distinguishing characteristics all important.

[0006] The new variety of nectarine tree of the present invention is a promising candidate for commercial development for a number of significant reasons, as will hereinarer be discussed in greater detail.

ORIGIN AND ASEXUAL REPRODUCTON OF THE NEW VARIETY

[0007] The present variety of nectarine tree hereof was discovered by the inventors in March 1993 in an experirnental block located near Selma in the San Joaquin Valley of central California as a cross between the “May Lion” nectarine tree and the “Summner Lion” nectarine tree. The new variety was asexually reproduced in 1995 by the inventors by grafting bud wood of the new variety onto two scaffold limbs of Nemiguard root stock in the experinmental block. The inventors have, since that time, observed the asexually reproduced growth of the new variety and witnessed that, in all respects, the resulting progeny are identical to that of the parent tree of the new variety in all respects.

SUMMARY OF THE NEW VARIETY

[0008] The nectarine tree of the new variety is characterized by producing a fiuit which is ripe for commercial harvesting and shipment approximately June 16 through July 1 in the San Joaquin Valley of central California, or about five to seven days earlier than the “Spring Bright” nectarine tree. The new variety of the present invention is perhaps most closely similar to the “Spring Bright” nectarine tree (United States Plant Letters Patent No. 7507), but is distinguishable therefrom by the aforementioned ripening date and in numerous other respects hereinafter to be set forth. The fruit of the new variety is more intensely colored than the fruit of the “Spring Bright” nectarine tree being nearly completely dark garnet red while the fruit of the “Spring Bright” nectarine tree is of a lighter orange red coloration. The frait of the new variety is larger in size than the fmit of the “Spring Bright” nectarine tree and is more firm in character.

Having thus described and illustrated our new variety of nectarine tree, what we claim as new and desire to be secured by plant letters patent is:
 1. A new and distinct variety of nectarine tree substantially as illustrated and described which is somewhat remotely similar to the “Spring Bright” nectarine tree (United States Plant Pat. No. 7,507), but from which it is distinguished by producing fiuit which are mature for commercial harvesting and shipment approximately five days to seven days prior to the “Spring Bright” nectarine tree, in the San Joaquin Valley of central California and which have a distinctive dark garnet red coloration over virtually its complete skin surface.
